This invention relates te improvements in a the, construction of arbors for the shell'rolls of-spinning and roving machines.

Heret'oi'ore, diiliculty has beenexperienced o where shell rolls have been employed, be

has "been attempted to lubricate the rolls and their arbors by forcing oil between the same by the use of a 'springbottom oil can,

inasmuch "as the lubricantis not evenly distributed by this method and, as a' consequence, the" rolls will run unevenly. I It has likewise'been proposed to'employhollow art bors and supply lubricant'from the arbors to,

their roll bearing portions ,by oil'duct's or wicks, but'in all such arrangements so far as-I'f am aware, the she'llfrolls' are'not properly lubricatedas the distribution of1the-lu ing' qualities are greatly impaired. In view of the foregoing it is,ther efore the primary obj e'ct' of the present invention to provide an arbor for shell rolls of'spinnin'g and other textile machines of such construction that a I 1 substantially n the}line'2 21o fFigure 1,

trib'u'ted to the surfaces to be lubricated in a" manner topreventthe distribution of a sur-j v lubricant will be supplied and evenlyldis- 7 plus amountof the lubricant and insure of 'ire'e and uniform rotationofthe shell rolls, as well "asi'avoiding' the Waste of'lub'ricant' and the contamination of thesupply thereof which'is retained within the hollow. a-rbor of I the presentinvention.- V v a Anotherbbject of the present invention is to providean' arbor for shell 'rolls of suchconstruction that lubricant may be -readily supplied thereto fromitime to time as occasion may require, without likelihood of overfilling thereserve space'for the lubricant and in this connection, ,the invention contemplates'the' provision of meansflwhereby the one sluplying the lubricant willbe apprised} of the fact that the arbor isQ-Siipplied/with, sufficient lubricant, when this condition e g ists.-

i Another objectof the invention is.t pro rolls will be lubricatedjto an extent to provide for their free and uniform rotation, this damage to the material. In other cases, it'

The lower end of the shank 25 of the stirrup is provided with a hook 30, and a square or rectangular eye 31 at the upper end of the shank 32 of a weight hook33 is engaged with the said -hook 30 and the bill 3a of-the said weight hook supportsa weight 35. I The numeral 36 "indicates a saddle which is provided with T v dependingspacedlugs 37 which engage the.

front and rear faces of the boss 8 of the arbor for the middle rolls L2, as clearly shown in Figure 2, and this saddle has a bifurcated portion 38 which extends above, and the members of which rest upon, the

upper'side of the boss 8 of the arborfor the baclc rolls 3, the saddle being held against displacement with relation to the arbor for the iniddle rolls through the en gagement' of the lugs 37 with the said boss 8 of the arbor and beingpi'ovided with an opening 39 through which lubricant may be introduced, this opening being positioned directly above the flaredupper end of the oil opening 20 in the said boss. Inasmuch as the saddle is bifurcated, its spaced portions will extend at opposite sides of the fiared upper end of the oil opening in the boss of the arbor for the back'rolls and,

therefore, due to thearrangement of the stirrup and saddle, oil may be supplied to all of the arbors without 'any 'difiiculty. The saddle 36 is provided in its upper side with a plurality of transverse notches 4:0

and a hook 41 corresponding to the hook 33 has its square eye 42 fitted over the said saddle with the upper Wall of the eye ,or slot adapted for engagement in the notches 4C0 interchangeably, depending upon the spacing of the rolls 2 and 3. The bill of the hook 41 supports a weight 43 corresponding to the weight 35. v
